Wow, a four-person bunk bed! This couple’s clever idea created more space in their one-bedroom apartment
Otso Alasko and Raisa Mattila built a permanent four-person bunk bed for their children in their one-bedroom apartment, using kitchen cabinets as the base.
Otso, how did you come up with the idea for this amazing bunk bed project?
We have four children in total, and our one-bedroom apartment has limited space. Where the bunk beds stand now, there used to be a built-in closet in poor condition that needed replacing anyway. The idea took shape when we started thinking about making a permanent custom solution in place of the closet.
Here’s what the space looked like before building the bed:

How did the construction progress?
I began by measuring the room, then sketched a bunk bed design using Ikea’s 3D software. I decided to build on top of Ikea’s standard kitchen cabinets because they matched the room’s dimensions well and were affordable. For the bunk bed’s headboards and partitions, I used the made-to-order sliding doors, made for the original closet, that were only four years old and still in good shape. I bought the bed bases from a furniture store and the frames from a hardware store. The ladders and lattices were installed by a carpenter—other than that, I built the bed myself.

How long did the project take in total?
It took a few weeks altogether. I spent about two to three weeks building, then the carpenter worked on it for another week. The children stayed in the room the whole time, so we had to re-open and close the work site daily and of course clean up after every session.


Are you pleased with the final result?
I’m really happy with it: it looks nice, and now we feel like we could want to live in our home for a long time. It’s also easy to convert the design into, for example, loft beds or desks when it's time to sell the apartment later on. Our neighborhood’s price per square meter is over 6,000 euros, and this bunk bed project has added several square meters of living space in our apartment.



How do the children like the beds?
They were really excited to see the bunk beds finished. Every week, they would ask if the project was nearly done, and for them it felt like nothing had happened, no matter how much we worked on it. They’re very happy with how it turned out, and it’s been a great setup for them, especially at this age as they love playing together.

Your project got a lot of love on social media. How does that feel?
Raisa made a reel about the beds on Instagram, and it got about half a million views. It was fun to see how much interest our project sparked! I think it's important to challenge the assumption that children always need their own rooms, and I think built-in beds might become more popular. Compared to ordinary bunk beds, they make much more efficient use of space.
